is php_self still ok?

[low tech]

Hi guys

I'm having a go at building a basic php navigation for my site and basically it's based on this

PHP Code:

basename($_SERVER["PHP_SELF"]) 


It's working, but a thought came to my head --- is this code reliable?

ie is this code still used? Is there some other newer way I should be using?

I just need file name to determine navigation

Depends on what you are using it for.
That will work for the accessed page, but not for inclusions. So the running script is PHP_SELF. You can probably save effort by using SCRIPT_NAME instead, but if you want to operate on a specific file regardless of inclusion levels, use the __FILE__ magic constant.

Hi Fou-Lu

Thanks for reply

Yeh navigation is in an include.

so I should use this right

PHP Code:

basename($_SERVER["SCRIPT_NAME"]); 


I grab the filename and echo nav content based on that -- just if else stuff

It's working on localhost, but I don't want to do it all only to find it's not reliable on server.

My script hinges on that one line really.

I don't know how to use the __FILE__ magic constant.

atm my include looks like this at start

PHP Code:

$currentFile = basename($_SERVER["PHP_SELF"]);
$parts = Explode('/', $currentFile);
$show = $parts[count($parts) - 1]; 


with rest of nav based on $show

SCRIPT_NAME should always be available in a web environment.
I'm not really sure what you are doing here. The $currentFile created using the basename will just be myscript.php, without any path, so the parts and show variables don't have any value.

Hi Fou-Lu

The $currentFile created using the basename will just be myscript.php,

Yeh, I saw that eventually. I've changed it now and removed the code that was being used to parse php_self.

Just learning as I go:-)

Thanks for yr help
